A kind of resistance to compression reducing double-wall corrugated pipe, including body, body include outward corrugated tube and inner tube, the outward corrugated tube bag
Include left part outer tube, left portion's bellows, middle outer tube, right middle bellows and right part outer tube, the left part outer tube, in
Between outer tube and right part outer tube be straight line body, left portion's bellows and right middle bellows are bellows body, left portion
The crest radial dimension of bellows and right middle bellows is gradually reduced setting to both ends respectively, and said inner tube, which is internally provided with, to be added
Strong core pipe layer, the outward corrugated tube are made up of outer layer bellows body, corrugated steel band and internal layer bellows body successively from outside to inside,
The internal layer bellows body is fixedly connected by adhesive linkage with inner tube outer circumferential walls.
Preferably, the left part outer tube, left portion's bellows, middle outer tube, right middle bellows and right part outer tube
It is integrally formed and outward corrugated tube is made.
Preferably, the adhesive linkage is made up of spaced flat segments adhesive linkage and raised section adhesive linkage.
Preferably, the length of the corrugated steel band extends reversely identical with the length bearing of trend of outward corrugated tube, corrugated steel
Around the central axis of body, circumferentially shape is uniformly set on internal layer bellows body outer wall band.
Preferably, said inner tube is inner layer polyethylene body, and outer layer bellows body is outer layer polyethylene bellows body, internal layer
Bellows body is interior layer polypropylene bellows body.
Compared with prior art, the beneficial effects of the utility model are：In body, left part outer tube, middle outer tube and
Right part outer tube is straight line body, and so, the both ends and centre of bellows can use flange facilitate ripple as supporting construction
The installation fixation of line pipe and stable support, effectively avoid transition in the middle part of bellows sagging；Corrugated steel band is arranged on outer layer bellows
Between body and internal layer bellows body, and around the central axis of body, circumferentially shape is uniformly distributed setting to corrugated steel band, increases
The strong overall resistance to compression external pressure ability of bellows, undulatory corrugated steel band also greatly strengthen the deflection degree of bellows, can
Larger flexure is born, is not influenceed by a certain degree of differential settlement in ground, extends whole service life length.This practicality
New structural design is reasonable, and critical external compressive resistance ability is strong, and deflection degree is good, and support is convenient, service life length.
